Electromotive force, abbreviated as E.M.F and denoted by $\varepsilon$, is not a force. It is defined as the energy utilized in assembling a charge on the electrode of a battery when the circuit is open.Simply, it is the work done per unit charge which is the potential difference between the electrodes of the battery measured in volts.
In particular, bathos is associated with anticlimax, an abrupt transition from a lofty style or grand topic to a common or vulgar one. This may be either accidental (through artistic ineptitude) or intentional (for comic effect). Intentional bathos appears in satiric genres such as burlesque and mock epic.
VANOS is a variator system that varies the timing of the valves by moving the position of the camshafts in relation to the drive gear. The relative timing between inlet and exhaust valves is changed. At lower engine speeds, the position of the camshaft is moved so the valves are opened later, as this improves idling quality and smooth power development.
